The electrical pin processing equipment according to claim 6, characterized in that: When the horizontal plate is in the upper dead center position, the vertical slide bar is in the upper end position under the action of the tension spring, and when the sliding block abuts against the outer side of the vertical slide bar, the sliding block drives the locking column to insert into the locking hole. As the horizontal plate moves downward, the cutting chamfering assembly first cuts the cylindrical material rod. After the cutting chamfering assembly cuts off the cylindrical material rod, as the horizontal plate continues to move downward, the horizontal plate abuts against the upper end of the vertical slide bar and drives the vertical slide bar to move downward. When the vertical slide bar moves downward and the sliding block abuts in the vertical cutting groove, the sliding block drives the locking column to completely disengage from the locking hole under the action of the second spring. At this time, as the horizontal plate moves downward, the cutting chamfering assembly chamfers the cutting end surface of the cylindrical material rod; when the horizontal plate moves upward from the lower dead center, the vertical slide bar moves upward under the action of the tension spring, and as the vertical slide bar moves upward, the sliding block passes through the vertical cutting groove through the transition inclined surface and abuts against the outer side of the vertical slide bar, and the locking column is inserted into the locking hole.

8. The electrical pin processing equipment according to claim 5, characterized in that: The outer side of the swivel block is provided with a guide cone surface at the opening of each locking hole so that the locking column can be inserted into the locking hole.

9. A working method of the electric pin processing equipment according to claim 1, characterized in that: The following steps are involved: First, control the horizontal plate to be in the upper dead center position, at which time the locking assembly is in the locked position; then pass the cylindrical material rod through the left and right rotating rings from left to right and measure the length to be cut; then control the left chuck and the right chuck to clamp the cylindrical material rod; then start the cutting and chamfering assembly and control the horizontal plate to move downward. As the horizontal plate moves downward, the cutting and chamfering assembly first cuts the cylindrical material rod. After the cutting and chamfering assembly cuts the cylindrical material rod, as the horizontal plate moves downward, the horizontal plate controls the locking assembly to be in the unlocked position, the horizontal plate continues to move downward, and the cutting and chamfering assembly chamfers the cutting end face of the cylindrical material rod; when the horizontal plate moves to the lower dead center, the cutting end face of the cylindrical material rod is chamfered, and the cutting and chamfering assembly is controlled to stop; then control the horizontal plate to drive the cutting and chamfering assembly to move upward, and the locking assembly is switched from the unlocked position to the locked position. When the horizontal plate moves to the upper dead center position, control the left chuck and the right chuck to release the cylindrical material rod, and continue to move the cylindrical material rod to the right to the set length, and repeat the above steps.
